Product liability claims, warranties also as guarantees made by MSA with respect to the product are voided, if it is not used, serviced or maintained in accordance with the instructions in this manual.

1.3 Safety and Precautionary Measures to be Adopted

Check function each day before use

Before each use, check the function and calibration of the device. Otherwise there is a danger that incorrect results will be displayed. The check is performed using a suitable calibration gas.

Perform a bump test each day before use

Perform a bump test before each day's use to verify proper operation. The device must pass the bump test. If it fails the test, perform a calibration before using the device.

Perform a bump test more frequently if the device is subjected to physical shock or high levels of contaminants. Also, perform a bump test more frequently if the tested atmosphere contains the following materials, which may desensitize the combusti-ble gas sensor and reduce its readings:

- Organic silicones

- Silicates

- Lead-containing compounds

- Hydrogen sulphide exposures over 200 ppm or exposures over 50 ppm for one minute.

Check minimum concentration of a combustible gas

The minimum concentration of a combustible gas in air that can ignite is defined as the Lower Explosive Limit [LEL]]. A combustible gas reading of "XXX” indicates the atmosphere is above 100 % LEL or 5.00 % vol CH4, and an explosion hazard ex-ists. Move away from hazardous area immediately.

Attention!

Attention!



OperationMSA

ALTAIR 4XGB 23

In such cases, the device LockAlarm feature activates.

3 Operation

3.1 Environmental Factors

A number of environmental factors may affect the gas sensor readings, including changes in pressure, humidity and temperature. Pressure and humidity changes af-fect the amount of oxygen actually present in the atmosphere.

Pressure Changes

If pressure changes rapidly [e.g., stepping through airlock], the oxygen sensor read-ing may temporarily shift and possibly cause the detector to alarm. While the per-centage of oxygen may remain at or near 20.8 Vol %, the total amount of oxygen present in the atmosphere available for respiration may become a hazard if the overall pressure is reduced by a significant degree.

Humidity Changes

If humidity changes by any significant degree [e.g., going from a dry, air conditioned environment to outdoor, moisture laden air], oxygen readings can be reduced by up to 0.5 %, due to water vapour in the air displacing oxygen.

The oxygen sensor has a special filter to reduce the effects of humidity changes on oxygen readings. This effect will not be noticed immediately, but slowly impacts oxygen readings over several hours.

When gas reading exceeds 100% LEL CH4, the device enters a Lock Alarm state , the combustible sensor shuts down and displays “xxx” in place of the actual reading. This state can only be reset by turn-ing the device off and on in a fresh air environment.

Attention!

A combustible gas reading of "100” indicates the atmosphere is above 100% LEL CH4 and an explosion hazard exists. Move away from con-taminated area immediately.

Check your national standard values for 100 % LEL. Some countries use 5 Vol % and some use 4.4 Vol % as 100 % LEL CH4.

MSAOperation

ALTAIR 4X24 GB

Temperature Changes

The sensors have built-in temperature compensation. However, if temperature shifts dramatically, the sensor reading may shift. Zero the device at the work site temperature for the least effect.

When in measure mode, the ♥ symbol is continuously displayed.

Finishing Calibration

(1) Close the valve on the regulator.

(2) Remove the calibration cap.

The calibration procedure adjusts the span value for any sensor that passes the ca-libration test; sensors that fail calibration are left unchanged. Since residual gas may be present, the device may briefly go into an exposure alarm after the ca-libration sequence is completed.

Autocalibration Failure

If the span calibration is unsuccessful:

- A sensor life indicator is displayed [Alarm symbol and ♥ symbol] to show the sensor has reached its end of life and should be replaced.

- The device will remain in alarm state until the button is pressed.

- The Alarm symbol and ♥ symbol will remain on the display until a successful calibration or sensor in question is replaced.
